Three main interrelated issues regarding the Arctic environment are climate change, changes in biological diversity, and the accumulation of toxic substances . The effects of these changes are becoming increasingly evident in the North.
What are the main threats to the Arctic?
The Arctic is under great threat from a multitude of environmental changes induced by human activities , most importantly through climate change, but also through pollution, industrial fishing, foreign species introduced to the area, nuclear waste and petroleum activity.
What are some problems in the Arctic?
- The temperature rise. ...
- Melting ice. ...
- Ocean acidification. ...
- Natural resources: challenges of exploitation and technological limits. ...

What bad things are happening in the Arctic?
Without urgent action to cut greenhouse gas emissions, the world will continue to feel the effects of a warming Arctic: rising sea levels, changes in climate and precipitation patterns, increasing severe weather events , and loss of fish stocks, birds and marine mammals.
Why is the Arctic in trouble?
Rising concerns
Arctic permafrost thaw is also escalating, releasing the potent greenhouse gas methane and spiking atmospheric levels, with profound global warming effects . Wildfires burn near the tundra-taiga transition in Siberia. Such fires are expected to become more common as the permafrost thaws, then dries out.
How can we protect the Arctic?
Reducing your carbon emissions and dependence on fossil fuels can help save the Arctic. Discover practical ways you can make a difference, from joining our campaigns to shopping greener at the supermarket and making your home energy efficient.
How are humans threatening the Arctic?
Air pollution affects tundra environments in different ways. ... And toxic mercury, sent into the atmosphere by coal-burning and industrial activity, is accumulating in the Arctic tundra, threatening both humans and animals who live in the region. Air pollution can also harm or kill the important food source of lichen.
How are humans helping the tundra?
Solutions . Cutting harmful, planet-warming pollution by switching away from fossil fuels is key to safeguarding Earth’s tundra habitats. Other measures include creating refuges and protections for certain species and regions while limiting or banning industrial activity.
Why should you go to the Arctic?
One of the main reasons to go to the Arctic is to see the Northern Lights (aurora borealis) , an unbelievable natural phenomenon where eerie green, pink and white lights dance across the night sky. During the Arctic winter, there are numerous amazing places where you can enjoy this spectacle in Lapland and Iceland.
Is the Arctic in danger?
Climate change poses the greatest danger to the Arctic and its wildlife. The Arctic is warming twice as fast as any place on the planet. ... The Arctic is also a target for oil and gas development both on land and in the ocean.
What would happen if the Arctic melted?
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet) . The ocean would cover all the coastal cities. And land area would shrink significantly. But many cities, such as Denver, would survive.
What causes Arctic ice to melt?
Melting ice speeds up climate change.
Global warming is causing Arctic ice to melt – ice reflects sunlight, while water absorbs it. When the Arctic ice melts, the oceans around it absorb more sunlight and heat up, making the world warmer as a result.
Is the Arctic really melting?
In September 2020, the US National Snow and Ice Data Center reported that the Arctic sea ice in 2020 had melted to an area of 3.74 million km 2 , its second-smallest area since records began in 1979.
Why does the Arctic warm faster?
Ice is more reflective and less absorbent of sunlight than land or the surface of an ocean. When ice melts, it typically reveals darker areas of land or sea, and this results in increased sunlight absorption and associated warming. Polar amplification is much stronger in the Arctic than in Antarctica.
How cold is the Arctic?
| Time of year Average (mean) temperature | North Pole South Pole | Summer 32° F (0° C) −18° F (−28.2° C) | Winter −40° F (−40° C) −76° F (−60° C) |
|---|
How long do we have to save the Arctic?
A new Nature Climate Change study predicts that summer sea ice floating on the surface of the Arctic Ocean could disappear entirely by 2035 . Until relatively recently, scientists didn’t think we would reach this point until 2050 at the earliest.
